oncd by the light of the lamp, under which circumstances its 

 tints are particularly pleasing. It is found in the vicinity of 

 Orthosia, throughout the whole of Caria, and in the neighbour- 

 ing localities ; but the most approved stones are those that 

 come from India. Some writers have given the name of " dead- 

 ened" u carbunculus to a lychnis of second-rate quality, and 

 similar in colour to the flower known as the " flower of Jove. " ! * 

 1 find other varieties also mentioned, one with a purple radiance, 

 and another of a scarlet 10 tint. It is asserted, too, that these 

 stones, when heated or rubbed between the lingers, will attract 17 

 cliaif and filaments of paper.

Carchedonia, 18 too, is said to have the same property, though 

 far inferior in value to the stones already mentioned. It is 

 found in the mountains among the Nasamones, 1 ' being pro- 

 duced, the natives think, by showers sent for the purpose from 

 heaven. These stones are fouml by the light of the moon, 

 more particularly when at full : in former days, Carthage was 

 the entrepot for them. Archelalis speaks of a brittle variety be- 

 ing found in the vicinity of Thebes ako, in Egypt, full of veins, 

 and similar to dying embers in appearance. 1 find it stated, 

 too, that in former times, driuking-vessels used to be made of 

 this stone and of lychnis: 20 all these kinds of stone, however, 

 oiler the most obstinate resistance to the graver, and, if used 

 ior seals, are apt to bring away a part of tho wax.

 ftone mentioned in Chapter li/J, which was prohahly a garnet or a ruby.

 varieties called Striped or Riband jasper, and Egyptian jasper.
